This invention relates to cellular cartons such as are employed for packaging eggs or the like.

It has for its object the provision of such a carton that can be made of a single blank of material such as cardboard and can be glued simply and inexpensively in the fiat to form a carton blank which can then be opened up and assembled easily for filling.

A further object of the invention is to provide such a carton in which the eggs or other objects which are packaged are supported in such a way as to provide adequate cushioning to minimize breakage with the least material and the simplest assembly.

These objects are obtained by the carton illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of the assembled carton;

Fig. 2 is a side elevational view of the carton partly in section showing the arrangement of the cross partitions;

Fig. 3 is an end elevational view of the carton;

Fig. 4 is a top plan View of the carton blank showing the scoring and cutting thereof;

Fig. 5 is a top plan view of the carton blank folded as in the first step of final assembly;

Fig. 6 is an end view taken from the line 66 of Fig. 5.

The carton blank indicated generally at l is made up of a top portion 2 from which depends a fastening flap 3 provided with hook members 4, side walls 5 and 6, a bottom and lower central partition-forming section consisting of bottom partition sections 1 and 8 and bottom-forming members 9 and Ill. There is also provided an upper cross partition and upper central partition-forming section comprising partition-forming sections II and I2 and the cross partitionforming sections I3 and 14. There is also a securing flap i5.

There is a line of scoring I6 between the top 2 and the fastening flap 3, on which the material is bent for assembly. There are also lines of scoring l1, l8, I9, 20, 2|, 22, 23, 24, 25, 26 and 21 between the various sections on which the material is bent either during assembling or setting up the carton.

The sections l3 and M are cut in a conventional manner, as shown at 28 and 29, to form cross partitions 30 and 3i, which swing downwardly, as shown in Fig. 1, and engage the bottom of the assembled carton to form cells to receive the eggs or the like.

The partition sections 1, 8, H and [2 form the central partition 32 of the finished carton. These pairs of partition sections 1, 8, and ll, 12, are hinged together along score lines 20 and 25, respectively. In the assembled carton they lie face to face with their hinge lines adjacent and parallel.

The pairs of partition sections are joined together by attachment extensions 33 and 34, which are identical in size and shape. These attachment extensions are cut out of one of each pair of partition sections with the cuts 35, 36, 31, 38, 39 and 40 adjacent the points of hinging of said pairs of sections, namely, the score lines 20 and 25. They project in the plane of the section of which they form an extension. In the assembled carton the extension 34, which lies in the plane of partition section [2, extends into the cut-away portion of partition section 1 which is formed by the cutting-out and removal from said partition section of the atachment extension 33. Because the attachment extensions 33 and 34 are of the same size and shape, the attachment extension 34 fits into and fills the cut-away portion where it is glued. The extension 33 likewise fits into the cut-out portion left by cutting out and removing the extension 34 from the partition section II and is glued in this position. Thus the various partition sections are joined to form a continuous rigid central partition 32.

By properly proportioning the upper and lower partition sections and the other sections, it is possible to give the carton the form shown with the bottom sections 9 and i0 slanting upwardly to the center partition from the walls 5 and 6 as best seen in Figs. 1 and 3, thus providing adequate cushioning for the contents of the carton. The partition constructed as shown assures the maintenance of thi form. To further assure against downward collapse of the bottom member there are provided extension foot members 4| and 42, which form downward extensions from the lower partition sections 1 and 8 and which are cut out of the bottom members 9 and I0 adjacent the score lines l9 and 2|.

In assembling the carton, the first step i to fold the blank to the position shown in Fig. 6.

folding along the lines of scoring 2|], 2|, 23 and 25. This brings the attachment extensions 33 and 34 to the assembled position and joins all of the partition sections 1, 8, II and I2, into a single partition. Prior to the folding appropriate applications of glue are made so that the atachment extensions 33 and 34 are fastened in position.

Thereafter, the carton is folded on the score line I9, which brings the securing flap 15 adjacent the upper portion of the wall 5; an appropriate application of glue having been made, this results in the complete gluing of the carton.

The carton remains in this form during shipping and only when it is desired to fill the carton is it erected. This is done by swinging the parts.v to the position shown in Figs. 1, 2 andv3.. The.

carton is first opened up and the partitions" 3t and 3| are pushed downwardly, where they iric-- tionally engage the bottom-forming,sections" 9iand ID. The end partitions fit into appropriate: slots 43 and are thus anchored. to preventloss of,

eggs or the like from the ends of the carton.

With the construction shown and describedgdt. is possible to assemble the carton with a minimum ofi gluing, and the central partition 32 is rigidand serves-tohold the carton in assembled set-up position, with thebottom sections raised above the" bottom line of the carton toprovide adequate V cushioning for the contents Y of the carton.

A single: form of the carton has been described. Ittwill beapparent, however, that modifications thereof can be made without departing from; the invention. The preferred form of theicarton has been illustrated or shown, but by Way of illustration only and not 1 by way of. limitation. It is intended-to be limited; only by the claims.
